It was the first successful method of making steel in quantity at low cost, It was the first successful method of making steel in quantity at low cost. It was a process "of converting pig-iron into steel at once by blowing a blast of air through the iron while in fusion till everything extraneous is expelled, and only a definite quantity of carbon is left in combination." Carbon, silicon, and other impurities are removed from molten pig iron due to oxidation in the blast of air in the special tilting retort called the Bessemer converter. The process revolutionised the iron and steel trade all over the world. However, it has now been largely superseded by other technologies.
